How to Fix HDMI Sound Not Working

A short audio-device fix path for hDMI Sound Not Working using output routing, permissions, and one clean reconnect.

Check output routing and mute state first, because the device may be working but sending sound somewhere else.

Common signs
Audio is too low, routed wrong, or missing entirelyAnother app or accessory changes the behaviorReconnects help only sometimes
1

Check output routing first

Make sure sound is going to the device you actually want to hear.

2

Test another app or file

That tells you whether the problem is global or tied to one service.

3

Disconnect conflicting devices

Bluetooth speakers, headsets, and docks can quietly steal the audio path.

4

Update driver or permissions

Low volume and missing sound can come from driver or app access issues.

5

Reconnect and retest

Give the device one clean reconnect after the routing path is fixed.

Get help faster if
  • The device fails on more than one port or app
  • The problem survives restart, reconnect, and update checks
  • There is visible hardware damage or moisture history
